| ciscoSeuMitigationMIB |
1.3.6.1.4.1.9.9.701 |
| This MIB reports the status of non-automatic and automatic,
rate-adaptive Single Event Upset (SEU) mitigation algorithms and
adjusts their parameters, as well as reports the effects of
those mitigations on memories, caches, and registers. SEU
mitigation allows Cisco IOS to run on radiation tolerant
hardware deployed in a geosynchronous Earth orbit satellites for
IP communications. One of the challenges in deploying equipment
in such an environment is the impact that radiation has on
digital circuits. A Single Event Upset (SEU) occurs when the
hardware is exposed to energetic ions and protons in the space
environment. The value stored in a bit of information can change
when a large enough charge is deposited on the digital circuit.
This leads to adverse effects in the operation of the software;
in this case Cisco IOS. While steps have been taken to reduce
the occurrence of SEUs through the use of radiation tolerant
hardware, these steps do not eliminate the threat. A critical
requirement in running IOS on such platforms is the utilization
of SEU mitigation strategies to reduce the impact of such events
on the operation of the Cisco device.
GLOSSARY
SEU : Acronym for 'Single Event Upset' : A hardware
disruption caused when hardware is exposed to energetic
ions and protons.
scrub : An algorithm that periodically refreshes memory, cache
or register contents by various means. |
